Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Shown in Fig. 1 to 3, a kind of multichannel steam injection mixing supercharging device, including：High steam chamber 1, it is internal with connecting
The high-pressure admission mouth 11 for connecing source of high pressure steam communicates, and high steam chamber 1 is closed cavity, and this cavity is pressed into by height
Steam ports 11 and high steam communicate, and the high steam entered from here is used as driving steam and used, and the bottom of high steam chamber 1
The vertical nozzle vapour locking 23 for running through several circular club shaped structures, the tops of all nozzle vapour lockings 23 by connecting portion 12 successively
With being connected through the push-and-pull portion 13 of high steam chamber 1 and executing agency 14, connecting portion 12 balances fixed nozzle vapour locking 23
Upper end.All connecting portions 12 and the push-and-pull portion 13 of rod-like structure connect, and such push-and-pull portion 13 can be with relatively high pressure vapor chamber 1
Slide up and down, can be in the position that pull bar 12 and high steam chamber 1 contact in order to prevent high steam from being revealed at push-and-pull portion 13
Put installation sealing ring.Because push-and-pull portion 13 and executing agency 14 are connected, and this transmission mechanism is control push-and-pull portion
About 13 equidistant movements, described executing agency 14 can be that Zhejiang Rui Pu thermal technology's automatic instrument(s)s Co., Ltd produces
《3820L series linear motion electronic formula electric actuators》Or others can realize the 13 reciprocal equidistance motion of push-and-pull portion
Executing agency, as long as can realize the reciprocal equidistant push-and-pull can in push-and-pull portion 13.The outer cover of the nozzle vapour locking 23
The jet pipe 22 fixed with high steam chamber 1, jet pipe 22 and high steam chamber 1 communicate, and the free end of jet pipe 22 is provided with injection
The circular hole of high steam, when nozzle vapour locking 23 is injected in circular hole, just the sealing of jet pipe 22 is blocked, when nozzle vapour locking 23 is taken out
When returning, high steam can spray from jet pipe 22 enters mixing chamber 3；Each described jet pipe 22 is fixed to one individually
Ejection cavity 2；The inside of the ejection cavity 2 communicates with being connected the low pressure admission mouth 21 in low-pressure steam source；In each single injection
Working condition in chamber 2 is：When as driving steam high steam when executing agency 14 withdraws upwards, just jet pipe 22
In opening open, such high steam can enter in mixing chamber 3 moment, so result in negative pressure state in ejection cavity 2,
Negative pressure just sucks the low-pressure steam at low pressure admission mouth 21, and the two arrives the opening after mixing and then from jet pipe 22 in mixing chamber 3
Place sprays.
Because performing structure 14, equidistant motion is only capable of opening a jet pipe 22 each time, and which achieves pass through control
System performs the purpose that structure 14 control keying jet pipe 22 one by one, and fully closed state is all jet pipes 22 not steamings, standard-sized sheet
State be exactly all jet pipes 22 simultaneously steaming.Accurately controlled into mixing chamber 3 by the can of executing agency 14
High steam amount, and then the low-pressure steam that can be come in indirect control from the injection of low pressure admission mouth 21.
Each individually ejection cavity 2 is connected by mixing chamber 3 with diffusion portion 4, from the mixed steam of the ejection of mixing chamber 3 know from experience into
Enter diffusion portion 4, by mixed steam again by the recovered part pressure loss of diffusion portion 4, after the steam pressure for reaching requirement
Heat user is supplied to use.All diffusion portions 4 are connected with converging after room 5 is connected with steam drain 6.The air intake for converging room 5 is straight
Footpath is linearly more than venthole diameter.
According to the property of fluid, in order to preferably reduce the vortex occurred when injection, and in order to allow as far as possible greatly
Measure motion of the molecular change into rule.Further, the exhaust steam end of the jet pipe 22 is Laval nozzle structure.At the same time it can also
Further, it is arc to allow the free end of the nozzle vapour locking 23, and the termination of this arc is in the mass motion of push-and-pull portion 13
During, high steam can regular gap between circular arc and jet pipe 22 enter, it is this to enter due to being annular
Gap is by the way that the driving steam of high pressure will not produce more turbulent flow, and the fluid motion of such rule can form stable bear
Pressure, and then the taste to steam after mixing has energetically meaning.
Driving steam after mixing low temp steam can be mixed in mixing chamber 3 in order to allow from mixing chamber 3 spray mixed vapour
With stable fluid, further, the center of the mixing chamber 3 is the arcuate nozzle tongue 231 of indent, the arc of this indent
It can allow fluid that there is stable mixed traffic, the bulk flow so flowed out from mixing chamber 3 is known from experience to be obtained preferably in diffusion portion 4
Diffusion.
, can be further in the diffusion portion 4 in order to allow the mixed vapour energy ditch of discharge out of mixing chamber 3 to be sufficiently mixed
Inside is provided with：The mixing tube 41 communicated with mixing chamber 3, mixed steam can be directly entered in mixing tube 41, because mixing tube
41 be diameter hollow pipe the same all the time, in the mixing tube 41 of sufficient length, mixed vapour can be allowed to obtain good mixing
Effect, then the mixing tube 41 and diffuser pipe 42 be connected, again passing by diffuser pipe 42 by well-mixed steam
Afterwards, just obtain sampling more preferable mixed vapour.
Operation principle：After high steam is entered from high-pressure admission mouth 11, then stored in high steam chamber 1, now
Control push-and-pull portion 13 to move upwards by performing structure 14, jet pipe 22 is thus opened one by one, from several jet pipes being opened
22 spray high steam, and then high steam can be rapidly entered in ejection cavity 2, and then low-pressure steam can be from the quilt of low pressure admission mouth 21
Injection enters to be mixed with high steam, is then discharged after the mixing of mixing chamber 3 from diffusion portion 4, finally all mixed vapours exist
Converge room 5 to do after fluid converges, discharged from steam drain 6.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
